Rear Main Seal
While my husband was home on R&R we decided to purchase a new vehicle. None of our other vehicles would allow us to put a car seat into them, and with a new baby, a new truck was a must have. We decided to buy a Nissan Xterra. Im not familiar with foreign vehicles at all, but he said it was a good truck to purchase so i agreed to it.
He bought a 2001 nissan xterra with about 114,000 miles on it.Truck has a salvaged title, owners claimed it was for theft. When we looked at it, there seemed to be an oil leak from the valve cover. When we bought it home, my husband repaired that issue. He also changed the oil. The truck didnt come with a manual, so he looked up what the required amount of oil for the truck was online. He ended up putting 4 quarts into it.
Now the truck started leaking ALOT of oil out of it right after that, so i took it into a shop, since my husband is back overseas. They said that it was leaking a decent amount of oil out of the rear main seal. That particular shop wouldnt touch it since its foreign. I called about five different places before i got a quote of about $750 to fix the rear main seal.
I ended up reading online that if the truck gets overfilled with oil that it will leak out of the rear main seal. Now my question is...Was 4 quarts of oil too much for an xterra and would it be coming out of the main seal if this much was put into the truck?
